VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 403,243, dated May 14,1889.

Application filed March 5, 1889.

To all whom it may concern:

Be it known that I, CHARLES M. BLYDEN- BURGH, a citizen of theUnitedStates, residing at Riverhead, in the county of Suffolk and State of NewYork, have invented certain new and useful Improvements in Vehicle-Springs, of which the following is a full and clear, description,reference being had to the accompanying drawings, forming part of thisspecification, in which Figure 1 represents a bottom view of avehicle-body, showing a portion of the runninggear and torsion-springs.Fig. 2 is a spring of modified form. Fig. 3 is an enlarged view of oneend of the bolster.

My invention relates to vehicle-springs and the means for securing themto the runninggear, whereby couplings, coupling-bolts, clips, &c., aredispensed with; and my invention consists, essentially, intorsion-springs having one end secured to the sill or bottom frame andthe opposite end bent inwardly at right angles, and also in constructingthe head-block or bolster, so that the free end portions of the springsmay be inserted in the ends of said head-block or bolster, or be securedlengthwise along its top or bottom, as I shall hereinafter fullydescribe and claim.

The object of my invention is to so construct and shape the springs of avehicle as to require no coupling-eye to be formed on the end which isusually attached to the running-gear, thereby dispensing with the use ofcouplings, bolts, clips, and like devices, and at the same time to sodispose of the springs that they will be efficient in action, the saidsprings being also cheaply and quickly made and applied.

To enable others skilled in the art to make and use my invention, I willnow describe the same and indicate the manner in which I carry it out.

In the said drawings, A represents the sill or bottom frame of thevehicle. B is the reach, 0 is the axle, and D is the bolster orhead-block, all of which may be of any wellknown construction, exceptthe bolster or head-block, which in the present case has its ends boredlengthwise, and provided with bushings of any suitable material, toprevent too rapid wearing away of the wood and the consequent enlargingof the end openings.

The springs E consist each of a torsion-coil,

Serial No. 301,852. (No model.)

of regular or irregular form, as shown in Figs. 1 and 2, and have oneend adapted to be secured, as at a, to the vehicle body or sill, and byclips I) or otherwise. The spring after being thus secured is coiled orbent in any desired manner to form the free or vibratlng arm 0, whichextends parallel with the sides of the bottom or sill, and has itsextremity or end bent inwardly at right angles with said arm, as at d,and inserted into the bored ends of the head-block or bolster D, asshown in Figs. 1 and 3, or may be secured on its top or bottom, wherebya pivot-connection is formed between the springs and bolster orhead-block and the liability of the springs being displaced beingreduced to a minimum.

Another important feature of the construction specified is that theright-angled portlon d and the arm portion 0 permit a free verticalaction of the body and yet secure a bearing in front of the body and ina direct line with the center of the coil, thus preventing or overcoming the twisting motion always present when the bearing is at theside of the center of the coil.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. Torsion-springs for vehicles, having one end bent inwardly parallelwith the bolster or head-block, in combination with a bolster havingrecesses for the bent ends of the springs, whereby a pivot-connecti onis formed, substantially as herein described.

2. The combination of a bolster or headblock having its ends boredlengthwise, and torsion-springs having their front ends bent inwardlyand passed into the bored ends of the bolster, substantially asdescribed.

3. The combination of a bolster or headblock having its ends boredlengthwise, and torsion-springs secured to the body of the vehicle andprovided with vibrating or free arms, which are bent at right angles attheir front portions and inserted into the bored ends of the bolster,whereby a pivoted connection is formed between the springs and bolster,substantially as described.
